Fort Clatsop was built by the Lewis & Clark Expedition to stay in during the winter of 1805-1806. The Visitors Center has a very nice museum/interpretive area and a gift shop with such things as steel & flint fire starting kits, replica's of some of the items the expedition would have carried.

Fort Humbolt was built in 1853 to try to keep the peace between Native Americans and settlers in the region. The Army was replaced by California militia during the Civil War, who moved the Native Americans to reservations.

The last time I visited Fort Ross was about 35 years ago, none of the buildings had any items in them. While these are not original artifacts, they make it much easier to envision daily life during the era the Fort was in use.
